SPECIFICATION formingpart of Letters Patent No; 739,996, dated September29, 1903.

Application filed June 10,1903. Serial No. 169.838. (No model.)

To all whom it mwy concern: I I

Be it known, that I, PHILIP T. DODGE, of WVashington, District ofColumbia, have invented a newand useful Improvement in merce, having thegeneral construction and arrangement of parts represented in UnitedStates Letters Patent No. 557,000, wherein the slug or linotype is castin a slotted mold mounted in a vertical and intermittingly-rotatingwheel. The mold stands in a horizontal position during the castingoperation, after which the wheel turns, carrying. the mold and the baseof the slug past a fixed trimmingknife, which determines the height ofthe slug, the motion continuing until the mold stands in a verticalposition with the contained slug directly in front of an ejector-bladewhich advances from the rear, pushing the slug or linotype before it outof the mold and between stationary knives for trimming its out sidefacesinto a receiving-galle y at the front. The slugs, which frequentlyadhere tightly to the interior of the mold,must be trimmed with extremeaccuracy. In the machines heretofore constructed it frequently happenedthat the pressure applied by the ejector to expel the slug would causethe mold-wheel and mold to spring forward, the result being an increasedresistance to the delivery of the slug and the presentation of the sluginaccurately to the trimming-knives and sometimes a permanent springingof the Wheel, so that the base of the mold was not carried closelyagainst the rear knife. The molds are commonly built up of a bodyportion screwed to the wheel, a vertically-adjustable cap portion, andtwo intermediate liners which determine the width and length of theslot, and thereby the thickness and length of the slug.

In practice the pressure applied to eject a strongly-adhering slug tendsto loosen or displace the mold in relation to the disk and to disturbthe proper relations between the cap,

body, and liners. The parts are also disturbed occasionally by thepressure of the ejector-blade if it chances to be out of adjust ment..To overcome these difliculties, I provide. a rigid banking surface-orsurfaces, against which the mold is rigidly supported at the frontduring the ejection of the slug.

Referring tothe drawings, Figure 1 represents a horizontal sectionthrough the moldwheel and adjacent parts of a linotype-1nachine havingmy improvement embodied therein. Fig. 2 is an elevation looking edgewiseagainst the mold-wheel and adjacent parts in the ejecting position, withthe mold seated against the supports or banking-pieces. Fig. 3 is ahorizontal section on the line 3 3 of Fig. 2. Fig. 4 is a face viewlooking for ward from the face of the mold toward the trimming-knivesand adjacent parts.

. Referring to the drawings, A represents the slotted mold, rigidlysecured in the vertical wheel 13, which is mounted to turn on an armextending laterally on the horizontal slide 0. The mold-disk receives anintermitting rotation from the driving-pinion D, and the slide C ismoved forward and back by the usual cam mechanism, first, when the moldis in thecasting position, and, second, when it is in position for theejection of the slug.

E represents the stationary back knife for trimming the base of the slugas it is carried by the passing mold.

F F represent the two vertical parallel knives, located directly infront of the mold, for the purpose of removing any fins or burs fromtheforward edge of the outgoing slug, insuring the uniform thickness ofits body portion.

G represents the horizontal ejector-blade, guided in the frame behindthe mold-wheel and operated bythe usual connections. After the slug hasbeen cast in the mold the disk revolves, carrying the mold and thecontained slug past the edge of the knife E, which trims the base of theslug flush with the mold. The disk continues its rotation until the moldassumes a vertical position directly between the ejectorblade and thefront trimmingknives, as shown in Fig. 1. As soon as the slug out of thematrices and in order also to bring the wheel in position to carry therear face of the mold closely against the back knife E. lVhen the moldhas reached the ejecting position, (shown in Fig. 1,) it is carriedforward by the movement of the slide C in order to present its frontedge and the contained slug as near as possible to the edges of theknives F, so that the slug may be accurately guided between them.

The foregoing parts are constructed and operate in the ordinary manner.

During the ejection of the slug the mold A,

1 which is built up of several parts, is unsupported at the front or, inother words, is supported wholly by the wheel to which its body portionis screwed. \Vhen, therefore, the pressure is applied by the ejector toexpel the slug, there is a tendency to spring the mold forward, to pushthe mold forward out of the disk, and to push the cap or outer portionof the mold away from the lower portion. It is to overcome thisdifliculty that my invention is intended.

In the form shown my improvement consists of two lugs or banking-piecesI I, rigidly seated in the main frame of the machine, preferably beyondthe ends of the side knives F, and in such position as to afford adirectsupport or hearing for the two ends of the mold at the front side.

It will be observed that when the mold reaches the ejecting position andis carried forward both its cap and its body portion bear at the two.ends on their front faces firmly against the supports I. \Vhen the moldis thus supported, it is prevented from springing forward, andconsequently the wheel is relieved from strain and the pressureprevented from displacing the mold or separating its members.

The essence of the invention lies in providing firm supports againstwhich the mold as a whole may be seated and sustained during theejection of the slug, and it is manifest that the support may be variedin form and arrangement at will, provided only it has themode of actionabove described. It is manifestly immaterial whether the supports areseparately constructed and applied to the frame, or whether they aremade in one piece, or whether they are simply suitable surfaces formedintegral with the frame.

Having described my invention, what I claim isj 1. In alinotype-maehine, a mold and a slug-ejector, in combination with meansfor rigidly supporting the mold against the thrust of the ejector.

2. In combination with the wheel and the mold mounted therein, anejector to expel the slug, and front supports against which the ends ofthe mold bear during the action of the ejector.

3. In a linotype-maehine, a inold movable in the direction in which theslug is ejected, a blade acting from the rear to eject the slug, and afixed front support to sustain the mold bodily in opposition to thethrust of the ejector.

4. In a linotype-maehine and in combination, the ejector, the sectionalmold, and rigid means bearing against both the cap and body sections ofthe mold to sustain them against the thrust of the ejector.

In testimony whereof I hereunto set my hand, this 29th day of May, 1903,in the presence of two attesting, witnesses.
